Abstract: The invention relates to a process for forming coatings or free-standing deposits of nanocrystalline metals, metal alloys or metal matrix composites. The process employs drum plating or selective plating processes involving pulse electrodeposition and a non-stationary anode or cathode. Novel nanocrystalline metal matrix composites and micro components are disclosed as well. Also described is a process for forming micro components with grain sizes below 1,000nm.

Abstract: Recrystallized lead and lead alloy positive electrodes for lead acid batteries having an increased percentage of special grain boundaries in the microstructure, preferably to at least 50%, which have been provided by a process comprising steps of working or straining the lead or lead alloy, and subsequently annealing the lead or lead alloy. Either a single cycle of working and annealing can be provided, or a plurality of such cycles can be provided. The amount of cold work or strain, the recrystallization time and temperature, and the number of repetitions of such steps are selected to ensure that a substantial increase in the population of special grain boundaries is provided in the microstructure, to improve resistance to creep, intergranular corrosion and intergranular cracking of the electrodes during battery service, and result in extended battery life and the opportunity to reduce the size and weight of the battery.

Abstract: Variable property deposit, at least partially of fine-grained metallic material, optionally containing solid particulates dispersed therein, is disclosed. The electrodeposition conditions in a single plating cell are suitably adjusted to once or repeatedly vary at least one property in the deposit direction. In one embodiment denoted multidimension grading, property variation along the length and/or width of the deposit is also provided. Variable property metallic material deposits containing at least in part a fine-grained microstructure and vari-able property in the deposit direction and optionally multidimensionally, provide superior overall mechanical properties compared to monolithic fine-grained (average grain size: >20 micron) or entirely amorphous metallic material deposits.

IPC: C25D5/50
Abstract: Polycrystalline materials are prepared by electrodeposition of a precursor material that is subsequently heat-treated to induce at least a threefold increase in the grain size of the material to yield a relatively high fraction of 'special' low .SIGMA. grain boundaries and a randomized crystallographic texture. The precursor metallic material has sufficient purity and a fine-grained microstructure (e.g., an average grain size of 4 nm to 5 µm). The resulting metallic material is suited to the fabrication of articles requiring high mechanical or physical isotropy and/or resistance to grain boundary-mediated deformation or degradation mechanisms.

Abstract: La presente invención se refiere a artículos o artículos autónomos recubiertos al menos parcialmente con materiales metálicos que llevan Co amorfos y/o de granos finos, substancialmente libres de porosidad, que contienen opcionalmente materiales particulados sólidos dispersados en los mismos. Las capas y/o parches metálicos electrodepositados que comprenden Co proporcionan, mejoran o restablecen la resistencia, el uso y/o la lubricidad de los substratos sin reducir el funcionamiento en condiciones de fatiga comparado con el substrato recubierto con Cr no recubierto o de espesor equivalente. Los recubrimientos metálicos amorfos y/o de granos finos que comprenden Co son particularmente adecuados para los artículos expuestos a ciclización térmica, fatiga y otras tensiones y/o en aplicaciones que requieren propiedades antimicrobianas e hidrofóbicas.
